From Francis OGER
@. . . . . . . Dear
Masatsugu,
I have received in due time your e-mail with questions
concerning Gilles Davidowicz. The following informations were given to me by
Elisabeth Sablé.
Gilles Davidowicz graduated, not exactly in astronomy, but in
geography, and he wrote a dissertation, which was supervised by Audouin
Dollfus, at Meudon Observatory. He specialized in planetary surfaces, and in
particular Mars.
His present profession is not specially related to astronomy.
In Société Astronomique de
France, he is a member of the
"commission" of planets. He is also a member of the elected counsel of
SAF. Perhaps you observed that the president and many members of that counsel
changed recently, and the present situation is not stable yet.
Apart from that,
Gilles Davidowicz is a member of the association "planète Mars" and, for that reason, was invited to visit
the american astronautics program for Mars.
Concerning the two
photographs in the last page of l'Astronomie, it seemed to me that they
were lacking some comments concerning, for instance, which part of Mars they
showed, what were the changes betwen June and September...
Presently, I am gradually moving my things to my new address, even
though there is still some repairing to do:
OGER Francis, 2B
rue Ronsard, 91230 MONTGERON.
It is a house with a fairly good view from the garden, especially
after I can get rid of an old poplar-tree, which is becoming dangerous. Some
horses are kept in the field just behind. Anyway, it is only 15 kilometers from
I am fully confident in Hiki for finding a good place for the CMO
meeting next summer. I still remember when he showed me the vegetable garden of
his school. In behalf of foreigners coming from countries with weak currency, I
can perhaps suggest to choose a place with affordable accommodations.
I still remember, several years ago, in Kiso Fukushima, a small
youth hostel where there was even a piano.
I go on working
with my colleagues in Tsukuba. Probably I told you, very long ago, that I am
working on mathematical logic and group theory. Presently, I am also applying
logic to non-periodic tilings, which are related to quasicrystals.
I attend nearly
every year, at the end of August or the beginning of September, the meeting of
Japanese model-theorists, but the exact date is always decided quite late, so
that I cannot tell you now when I go to Japan, and if I can go to the CMO
meeting With best wishes for all of you.
P.S.
Concerning the recently discovered comet C/2002 C1 (Ikeya-Zhang), is it the same Ikeya as in Ikeya-Seki, very long ago?

@. . . . . . . . Dear
Masatsugu,
It is nice to know that you met with such famous people as
Stephen Hawking and Roger Penrose (I guess it is the name of the man who helped Stephen
Hawking to go to toilet, since I did not hear of anybody else who was both
interested in tilings and relativity, and worked in an
Perhaps you know
the case of Kurt Gödel, who was a famous specialist of mathematical logic,
and afterwards also became interested in relativity. At the end of his life, he
had some mental problems and died of starvation, because of his fear of poison.
Albert Einstein was one of his last remaining friends, and his death probably
made Gödel's condition worse.････
More than 15 years
ago, I met in
Thany you for the
information concerning Ikeya and Seki. One of my friends especially told me her
admiration for Ikeya, as a simple worker who went observing stars after his
work.
With best wishes.
